- This invention relates to the packaging of electrical components, particularly of the type having terminal pins in a so-called “single-in-line” configuration, that is a row of terminal pins protruding in substantially the same direction from a single side of the component body.
- electrical components particularly of the type having terminal pins in a so-called “single-in-line” configuration, that is a row of terminal pins protruding in substantially the same direction from a single side of the component body.
- Such an electrical component is that hereinafter referred to as being "of the kind described”.
- MOS metal-oxide semi-conductor
- Fig. 1 is a cross-sectional view through a container.
- the container comprises a transparent tube 1 of plastics material having a body receiving portion 2 and a terminal pin receiving portion 3.
- the tube is provided with a coating of an anti-static agent which is intended to prevent the build up of a static electrical charge on the tube and consequent damage to a component upon contact with the tube.
- the anti-static coating is not always reliable and there remains the possibility that the components may be damaged by a static electrical discharge.
- FIG. 2 A similar container, but adapted for a multi-lead component, is shown in Fig. 2.
- the container comprises an elongate tubular member 1 of transparent plastics material, having a body receiving portion 2 and a terminal pin receiving portion 3.
- FIG. 1 Another known type of container is the same shape as those shown in Figs 1 and 2, but is made of an electrically conductive plastics material. While this tube does prevent static discharges from occuring, the electrically conductive plastics material is opaque and it is therefore not possible to inspect the components held in the container without first emptying the container. Furthermore this container is relatively expensive since it is made fully of conducting material.
- a container for loosely housing at least one electrical component of the kind described comprising an elongate tubular member having a first hollow portion for receiving the said body of the or each said component, and a second hollow portion for receiving the said terminal pins of the or each said component, wherein substantially only those portions of the said tubular member which are contactable by a said component when housed therein are electrically conductive, the tubular member being otherwise substantially transparent, said conductive portions being electrically interconnected.

- the electrical interconnections are provided at one or both ends of the container; however it will be appreciated that there are other possible arrangements. While an electrical connection at each end of the tube is preferred, it is possible to provide only a single connection at any point along the tube.

- the container may be provided with a plurality of upstanding conducting ribs on the external surface of the tubular member, arranged so that when two such containers are juxtaposed side by side it is not possible for any non-conductive portions of the containers to contact each other. This reduces the amount of static that is generated in a stack of such containers since the contact between two containers is either between two conductive portions or a conductive and a non-conductive portion.

- the body receiving portion 2 extends further on the side of the container bearing the step 4 than the side bearing the rib 5 so as to define a space 7 for receiving a mounting tab or a heat sink of the component.
- Figures 6 (a) - (f) show a component 8 housed within the container of the embodiment shown in Figure 3, the component being in a different position in each figure.
- the component has a main body portion 9, a row of terminal pins 10 extending from one side of the component, and a heat sink/mounting tab 11.
- the component can only contact the walls of the container in a number of selected regions.
- the body 9 of the component is unable to contact the window 6 of the body receiving portion, while the terminal pins 10 are unable to contact the walls of the terminal pin receiving portion 3.

Description
- This invention relates to the packaging of electrical components, particularly of the type having terminal pins in a so-called "single-in-line" configuration, that is a row of terminal pins protruding in substantially the same direction from a single side of the component body. Such an electrical component is that hereinafter referred to as being "of the kind described".
- Some components of this kind, for example metal-oxide semi-conductor (MOS) integrated circuits, are highly susceptible to static electrical charges and must be packed in anti-static or conducting containers so as to prevent the application of a static charge to one of the terminals of the component which could cause an internal electrical breakdown.
- One known type of container for components of the kind described is shown in Fig. 1 which is a cross-sectional view through a container. The container comprises a
transparent tube 1 of plastics material having abody receiving portion 2 and a terminalpin receiving portion 3. The tube is provided with a coating of an anti-static agent which is intended to prevent the build up of a static electrical charge on the tube and consequent damage to a component upon contact with the tube. However, the anti-static coating is not always reliable and there remains the possibility that the components may be damaged by a static electrical discharge. A similar container, but adapted for a multi-lead component, is shown in Fig. 2. Again the container comprises an elongatetubular member 1 of transparent plastics material, having abody receiving portion 2 and a terminalpin receiving portion 3. - Another known type of container is the same shape as those shown in Figs 1 and 2, but is made of an electrically conductive plastics material. While this tube does prevent static discharges from occuring, the electrically conductive plastics material is opaque and it is therefore not possible to inspect the components held in the container without first emptying the container. Furthermore this container is relatively expensive since it is made fully of conducting material.
- It would clearly be desirable to provide a container for components of the type described wherein the danger of damage due to static discharges is minimised, but which allows components held within to be inspected.
- According to the present invention there is provided a container for loosely housing at least one electrical component of the kind described, said container comprising an elongate tubular member having a first hollow portion for receiving the said body of the or each said component, and a second hollow portion for receiving the said terminal pins of the or each said component, wherein substantially only those portions of the said tubular member which are contactable by a said component when housed therein are electrically conductive, the tubular member being otherwise substantially transparent, said conductive portions being electrically interconnected.
- Clearly such an arrangement, at least in its preferred forms, provides a container which protects the components housed therein from static discharges while allowing the components to be observed. Furthermore the container requires only a small amount of conductive material, thus reducing the cost of the container and also permitting the components to be seen.
- Preferably the parts of said tubular member defining the body receiving portion are formed substantially of electrically conductive material, apart from a transparent window whereby said components may be inspected, said window being non-contactable by said components, and wherein said terminal pins are unable to contact the parts of said tubular member defining said terminal pin receiving portion.
- Preferably the tubular member is provided with a longitudinally extending inwardly directed conductive rib at the junction of said body receiving and terminal pin receiving portions, said rib serving to define a boundary of said window and to prevent said terminal pins contacting said window and said terminal pin receiving portion.
- As stated above, the conductive portions of the container are electrically interconnected, and this results in the conductive portions of the container having uniform conductivity thereby avoiding differences in potential between different conductive portions which might cause short-circuiting of the components.
- Preferably the electrical interconnections are provided at one or both ends of the container; however it will be appreciated that there are other possible arrangements. While an electrical connection at each end of the tube is preferred, it is possible to provide only a single connection at any point along the tube. Indeed connections between different adjacent pairs of conductive portions could be provided at different positions.
- The container may be formed from suitable plastics material, preferably PVC. The electrically conductive portions thereof may be formed in any suitable manner, but it is preferred to form them by incorporating carbon particles in the material forming the container. The transparent parts of the container may be made anti-static if desired, while still remaining substantially transparent, for example by providing them with a transparent anti-static coating.
- Additionally the container may be provided with a plurality of upstanding conducting ribs on the external surface of the tubular member, arranged so that when two such containers are juxtaposed side by side it is not possible for any non-conductive portions of the containers to contact each other. This reduces the amount of static that is generated in a stack of such containers since the contact between two containers is either between two conductive portions or a conductive and a non-conductive portion.
- Preferably these ribs are provided on all the outwardly projecting corners of the tubular member adjacent a transparent non-conductive portion.
- Some embodiments of the invention will now be described by way of example and with reference to the accompanying drawings in which:-
- Figure 3 is a cross-sectional view of a container according to a first embodiment of the invention,
- Figure 4 is a view similar to Figure 3 showing a modification of the embodiment of Figure 3,
- Figure 5 is a perspective view of one end of a container of the embodiment of Figure 3,
- Figures 6 (a) - (f) show a component of the kind described housed within a container of the embodiment of Figure 3,
- Figure 7 is a cross-sectional view of a container according to a second embodiment of the invention,
- Figure 8 is a perspective view of one end of a container of the embodiment of Figure 7,
- Figures 9 (a) - (h) show a component of the kind described housed within a container of the embodiment of Figure 7, and
- Figure 10 shows in a cross-sectional view a further modification of the embodiment of Figure 3.
- Referring first to Figure 3 there is shown a container in the form of an elongate
tubular member 1 made of plastics material. The tubular member is comprised of aportion 2 for receiving the body of a component of the kind described and aportion 3 for receiving the terminal pins of a component. The terminalpin receiving portion 3 is formed of a transparent plastics material, such as for example PVC, while thebody receiving portion 2 is formed of an opaque conductive plastics material. At the junction of the body receiving and terminal pin receiving portions there is provided on one side of the container an inwardly directedstep 4 and, on the opposite side of the container, an inwardly directedrib 5. Both thestep 4 andrib 5 are formed of conductive material and extend the full length of the container. Adjacent to therib 5, thebody receiving portion 2 is provided with a window 6 of transparent plastics material through which components housed in the container may be inspected. - The
body receiving portion 2 extends further on the side of the container bearing thestep 4 than the side bearing therib 5 so as to define a space 7 for receiving a mounting tab or a heat sink of the component. - Figures 6 (a) - (f) show a
component 8 housed within the container of the embodiment shown in Figure 3, the component being in a different position in each figure. The component has amain body portion 9, a row of terminal pins 10 extending from one side of the component, and a heat sink/mounting tab 11. As can be seen from Figure 6, because of the cross-sectional shape of the container, the component can only contact the walls of the container in a number of selected regions. In particular it will be noted that thebody 9 of the component is unable to contact the window 6 of the body receiving portion, while the terminal pins 10 are unable to contact the walls of the terminalpin receiving portion 3. Consequently to protect the component from static discharges it is only necessary to render conductive those portions of the container that a component may contact. The remaining parts may be left transparent, thus reducing the cost of the container and allowing components housed therein to be inspected. - As will be seen from Figure 5, the tubular member is provided with an additional ring of electrically
conductive material 12 at one or both ends which electrically interconnects the conductive portions. In the absence of such a provision it would be possible for two conductive portions of the container to be at different potentials, and if an electrical component were to contact two such portions simultaneously a potential difference would be applied across the component and it could be damaged. - There may also be provided two end plugs (not shown) made of a suitable plastics material and each having a projecting portion shaped to fit within an end of the tubular member and a rim which abuts the end of the tubular member. It would of course be possible for the aforementioned means electrically interconnecting the said conductive portions to be provided on one or both of the end plugs.
- The tubular member is formed from a plastics material such as PVC and is generally transparent except for the electrically conductive portions thereof. The electrically conductive are preferably formed by incorporating a conductive material, e.g. carbon particles, in the plastics material.
- Figure 4 shows a modification of the embodiment of Figure 3 in which the conductive material extends to the terminal pin receiving portion to provide added protection. Such a modified container may be useful for housing components having longer than usual terminal pins which may therefore contact the base of the terminal pin receiving portion. The modified container shown in Figure 4 is provided with, in addition to the window 6 in the body receiving portion, a
lower window 13 in the terminal pin receiving portion through which the terminal pins may be inspected. It will be appreciated that components housed within the container cannot contact either of these windows by virtue of the shape of the container, and in particular the provision of the inwardly directedconductive rib 5. - Figure 7 shows a second embodiment of the container which is particularly suited for housing multi-lead tab mounted components of the kind shown in Figure 9. The main difference between the embodiments of Figures 3 and 7 is in the shape of the terminal pin receiving portion. In the embodiment of Figure 7 the terminal
pin receiving portion 14 is much wider than the corresponding portion of the container shown in Figure 3. - The container shown in Figure 7 comprises a tubular member having a terminal
pin receiving portion 14 and abody receiving portion 15. At the junction of these two portions there is provided on one side of the tubular member an inwardly directed step or ledge 16, and on the opposite side of the tubular member an inwardly directedrib 17. Both the step or ledge 16 and therib 17 are formed of conductive material and extend the full length of the tubular member. Thebody receiving portion 15 is provided with a restrictedneck section 18 in which, in use, is located the mounting tab of a component and which generally restricts the movement of a component housed within the container. - The
body receiving portion 15 is formed of opaque conductive plastics material, except for a transparent window 19 provided adjacent theconductive rib 17. The terminalpin receiving portion 14 is formed of transparent plastics material. - Figures 9 (a) - (h) show a component housed within the container shown in Figure. 7 in various different positions. As will be seen from Figure 9 no matter what position the component takes up, it cannot contact the transparent window 19 or the walls of the tubular member forming the transparent terminal
pin receiving portion 14. - As described above with reference to the embodiment of Figure 3, the conductive portions of the container are electrically interconnected by, for example, a ring 20 (Figure 8) of conductive material provided at one or both ends of the tubular member. As before end plugs may be provided to seal the container.
- One of the major causes of static charge being present on such containers is friction occuring between the non-conducting portions of two such containers when they rub against each other. It is therefore desirable to prevent the non-conducting portions of one container from contacting the non-conducting portions of another when they are juxtaposed side by side. Figure 10 shows a modified form of the container shown in Figure 4 which meets this requirement. The container is provided with bulbous ribs of conductive material extending longitudinally along the outwardly directed
corners 21 of the tubular member adjacent the upper and lowertransparent windows 6, 13. An additional bulbousconductive rib 22 is preferably provided adjacent the above described inwardly directed conductive rib. - As can be seen from Figure 10, which shows two such containers juxtaposed with their non-conductive portions facing each other, the effect of
bulbous ribs transparent windows 6, 13 of the two containers cannot contact one another. In a stack of such containers it will be appreciated that the only contact between any two containers will be between either a conductive portion and a conductive portion, or between a conductive portion and a non-conductive portion, but not between two non-conductive portions. - If the container has a different distribution of non-conductive material from that of the container shown in Figures. 4 and 10, e.g. Figure 3, then more bulbous conductive ribs may be necessary to achieve the same effect. Preferably a bulbous conductive rib will be provided at each outwardly directed corner adjacent a portion of transparent non-conductive material.
- It is to be clearly understood that there are no particular features of the foregoing specification, or of any claims appended hereto, which are at present regarded as being essential to the performance of the present invention, and that any one or more of such features or combinations thereof may therefore be included in, added to, omitted from or deleted from any of such claims if and when amended during the prosecution of this application or in the filing or prosecution of any divisional application based thereon.
